The best and safest way to inflate a bicycle tire
to the correct pressure is with a bicycle pump
which has a built-in pressure gauge.
WARNING
There is a safety risk in using gas station air
hoses or other air compressors.
They are not made for bicycle tires. They move
a large volume of air very rapidly, and will
raise the pressure in your tire very rapidly,
which could cause the tube to explode.
Tire pressure is given either as maximum
pressure or as a pressure range. How a tire
performs under different terrain or weather
conditions depends largely on tire pressure.
Inflating the tire to near its maximum
recommended pressure gives the lowest rolling
resistance; but also produces the harshest ride.
High pressures work best on smooth, dry
pavement.
Very low pressures, at the bottom of the
recommended pressure range, give the best
performance on smooth, slick terrain such as
hard-packed clay, and on deep, loose surfaces
such as deep, dry sand.
Tire pressure that is too low for your weight and
the riding conditions can cause a puncture of the
tube by allowing the tire to deform sufficiently to
pinch the inner tube between the rim and the
riding surface. This may also result in damage.
